To all whom it may Concern.'

Be it .known that I, LINDLEYCLARK, a citizen of the United lStates,residing at Xenia, in the county of.k Greene -and'State of Ohio, haveinvented certain new and useful Improvements in Machines forHar-vestingGrain, of which the following is a specilication, reference beinghadtherein Vto the `accompanying drawing."

My invention relates to machines for-harvesting grain.

In my former inventionin connection with grain binders, as set forth inmy Patent No. 942,614, of Dec. 7th, 1909,Y I :provided a machine which'would bind the graininto bundles while in upright position as it wascutfrom the ground. Throughout' the operation the grain was maintainedin an'upright position.

My present inventionis animprovement, or more strictly speakinganaddition, to what was claimed,-described and illustrated in theaforementioned patent.

The object of my presenti invention is to take the bundles of grain as4delivered by the machine of the former inventionand fassemble suchbundlesv in an uprightposition in Va suitable location and lthendeposita predetermined number of bundles in a group on end so that thispredetermined number of sheaves or bundles will constitute the ordinaryshock, thuseliminating *l the necessity for Vassembling 'the sheaves as4deposited on the ground by hand labor and'puttingthem into a singleshocks yThis will result in large economy in man-ual' labor, in savinglfof grain througha minimum of handling and therefore a minimum ofshattering, and in a saving in `str'awthrough a perfect cutat rightangles to* the direction fof growtlrof Vthe grain.

Upon the' passage ofthis'pslieafpast the rearextremity of 'iregudee Yes'. adj-atene the damper it 'teenies-'ff meentein contact with the projections or lugs 34, 84 and accordingly drawsthat lug toward the rear of the machine in the direction of movement otthe bundle or sheat. 1n doing so it turns the fingers 88, 38 on thepivotal point 35, thus moving the noses 52, 52 and the accompanyingguides 88, 83 to the opposite sides of the delivery trough so that thesucceeding bundle which has in the meanwhile been gathered together andtied by the approprite mechanism will pass to the lett hand side of thisguiding mechanism 38, 83, being impelled along the delivery trough bythe sweeper 26 which has returned to its initial position to impel italong the trough like the tirst sheai2 or bundle was moved until thesecond sheaiis placed into the dumper at the rear ot the deliverytrough. This operation is continued successively with sheat', irst goingto the right and then to the left until sin sheaves have been placed inthe dumper mechanism on the right hand side and six on the left handside. Upon the full twelve being properly located, one-half respectivelyon each side of the dumper mechanism, a trip lever 41 is pulled so thatit coincides with the longitudinal axis or the dumper, thus allowing thedumper bottoms 37 and 38 to drop precipitantly so that they hang at apeipendicular7 thus depositing the twelve sheaves ot grain in one shockwith the grain sheaves on end.

To explain in greater detail as to the operation of this mechanismstarting from the source of power, 11 is the grain ejector utilized inthe former mechanisin'which is fixed to the shaft 18 on which is alsohired the master gear 12. Tl master gear 12 carries the arm 14 uponwhich is located a pin 15. rllhis pin 15 comes in engagement with thecam surface 16 on the lever 177 serving to move the lever 17 a slightdistance to the lett as the master gear 12 moves anticlockwise togetherwith the arm 14. rEhis slight movement ot the arm 17 nieves it fromengagement with the nose 18 ot the clutch 20, thus unlockin that clutchfor future action. rthis arm 1 is normally held in engagement with theclutch 20 at its nose 18 by the spring 32.

rllhe member 4G connected to the sprocket wheel 22 carries upon it thespring 23 which serves to keep the clutch 2O in a predeterminedposition. r the sprocket 22 turns loosely upon the shaft 21. The'sprocket 22 carries the pin 48 which is adapted toy engage the lug 24et the clutch 2O which keyed to the shaft 21. Upon the engagement of themoving linger 48 with the lug 24 on Vthe clutch 2O and upon the removalot the arm 17 from the path ot the nose 18 ot the clutch 2O thel pin 48will cause the clutch 20 to travel and thereby carry with it in thecourse of its revolution the sha-.tt 21 to which is attached the sweeperand acent mechanism,

thus causing the sweeper to move in a predetermined way to gatherabundle into the delivery trough past the guide arms and thence into thedumper.

Method of operation.

r1`he grain is cut and delivered standing to the conveyer 3. lt isthence conveyed to the packing and tying mechanism generally designatedby the numerals 4, 5, 6, 7 8, 9, 10 and 11. Upon the delivery into thetrough at the mouth 42 of the completed bundle the sweeper 26 moves inbehind the bundle by reason of the tact that the pin 15 has come incontact with the cam surface 16, moved the arm 17 out of engagement withthe nose 18 (see Figs. 6 and 7), thus allowing the spring 23 to throwthe clutch 20 outward from the shaft 21 to which it is keyed, bringingthe lug 24 of the clutch 20 into the path of the moving pin 48 fixed tothe sprocket 22, which sprocket is operated by the chain 50. rlhe chain50 derives its motion in the customary manner from the bull wheel 47.Upon the placing oi this lug 24 in the path of 48, 48 picks up theclutch 20 and its att-ached shaft 21 and revolves the same apredetermined distance about the shaft 21 carrying with it the sweeper26 along the line of the arrow through the delivery trough until thebundle is swept into the dumper, when the arm 26 is withdrawn along thepath indicated by the dotted line in Fig. 5. rlhe sweeper arm then comesto restan appreciable time while waiting for a new bundle to be tied anddelivered through the mouth 42 of t-he delivery trough. rhis appreciablepause is secured by having 17 return to its initial position by thespring 32 which is attached to the frame work supporting the shaft 21 sothat the end of 17 will come in contact with 18 and restore it to itsnormal locked position from which it first started, thereby permittingthe pin 48 on the sprocket 22 to pass by the lug 24 and over the body ofthe clutch 2O without moving 2O nor its attached shaft 21, 48 thuspasses around until the pin 15 on the arm 14 again engages thecamsurface 16 and throws 17 out of engagement with 18, thus permitting theclutch to fly outward again, as in the position shown in Fig. Y7, readyto engage 48 as it travels in its course around 21. 22and 48 are, ofcourse, constantly revolvino'.

Thus.3 wehave a' series of packing'arms 28 pressing the bundles irst toone sidefofthe delivery trough into one side of the dumper andthen tothe other side of the delivery trough into the other side of the dumper,these sweeper arms passingy between the guiding fingers 33 33 andpausing an ap preciable time while a new bundlel is being prepared t'orthem to sweep into the dumper. hilhen the dumper is ull the arm 41 ispulled by the wire 55 leading to the operators seat which serves to dumpthe twelve bundles onto the ground in the shape of a completed shock.

While I have shown and described one embodiment of my invention it willbe understood that the same has been chosen for purposes of illustrationonly, andwthat I do not desire to be limited to the details ofconstruction shown and described, for obvious modifications will occurto a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In a grain binder, a moving means turning about a shaft, sweeper armsfixed to said shaft superimposed one above the other, a delivery trough,guiding'ngers in said delivery trough between which said sweeper armspass, and means for intermittently moving said sweeper arms to passbetween said guiding fingers and through said trough, whereby bundles ofgrain may be moved through said delivery trough.

2. In a grain binder, a moving means turning about a shaft, sweeper armsfixed to said shaft superimposed one above the other, a delivery trough,guiding yfingers in said delivery trough between which said sweeper armspass, and means for intermittently moving said sweeper arms to passbetween said guiding fingers and through said trough whereby bundles ofgrain may be moved through said delivery trough, and means for movingsaid guiding fingers from one side to the other successively as bundlesof grain are passed through said delivery trough, whereby said bundlesare guided al- Copies of this patent may be\ obtained for ive centseach, by addressing' the ternatelv to the respective sides of said wheelfor engaging a clutch, a lug, one end of which is adapted to engage alocking arm, means to keep said lug in unlocked position, a locking arm,means to keep said locking arm in position to clutch said lock, meansfor throwing said locking arm out of engagement with said clutch, asweeper arm afixed to a shaft to which said clutch is aliixed, wherebywhen the sprocket and clutch in its unlocked position engage one anotherthrough the engaging means the sweeper arm will be moved in itspredetermined path.

4. In a sweeper mechanism, a source of power, a. chain from the sourceof power to a sprocket moving about a shaft, means on the sprocket forengaging a clutch aiiixed to said shaft, a lever attached to said shaftcarrying the sweeper arm, another lever turning on a iXed point at oneend and attached pivotally to one end of the sweeper arm to guide saidend, means for holding the clutch normally in unclutching position,means for locking said clutch, and means for throwing out of engagementthe locking mechanism of the clutch, a sprocket wheel carrying saidmeans to throw out of engagement the locking arm driven from the samesource of power first-mentioned, whereby the entire mechanism willopera-te in harmony and the sweeper arm will move in a predeterminedpath.

In testimony whereof, I affix my signature.
